You get the improved shot-to-shot consistency of a heavy-barreled design, plus the awesome stability and comfort of a thumbhole stock. Stock and fore-end are crafted of durable laminated hardwood, and this deadly accurate single shot has a full 24" of bullet-stabilizing bull barrel. The Ultra Varmint Thumbhole comes chambered in three popular varmint extinguishers: 223 Remington, 22-250 Remington and 243 Win. The transfer bar system prevents accidental discharge.
